Liberty Science Center is a wonderful place to visit. It has a lot of scientific information that can be valuable. I LOVE Liberty Science Center. On the disease train we learned about HIV. It is a retrovirus that causes HIV. It is very sad when people die from HIV. A few years ago a little girl had HIV. She lived until she was 19. Everyone was sad because she was a caring and sweet little girl.

Next we did a experiment. First we went in to the experiment room and got our lab coats and goggles. Second we went to the table and the man gave us 2 paper towels and a testing case. It was labeled 123 and 4+ and 5-. 1. We took 1 drop from the 1 testing tube. 2. We took 1 drop from the 2 testing tube. 3. We took 1 drop from the 3 testing tube. Next we put one drop into each testing box. Some grew some started to wrinkle. We put the coloring in each and 2 changed colors That means that patient number 2 had HIV. In the movie Sammy's Escape the environmental changed and caused some sea creatures to die. The little people opened the emergency door and all the creatures were free. The humans poured the oil in the water and many of the animals were dying. Some little people wanted the animals to survive so they forced the manager to open the emergency door and free the animals. As you can see this is what I learned and did at Liberty Science Center. It was super fun and I will go back with my family. If you went to Liberty Science Center what did you do and what did you learn??
